Abstract
The purpose of this study was to calculate and compare (1) knee loads, (2) muscle-specific contributions to knee loads, and (3) effects of knee flexion angle on knee loads and muscle-specific load contributions during a forward jump-landing task in people with and without chronic ankle instability (CAI). Eight CAI patients and seven healthy controls performed a forward jump-landing task. We collected 3D kinematics, ground reaction force, and muscle activation and used musculoskeletal modeling. The results showed that only healthy controls exhibited an association between knee flexion angle and knee compressive impulse (r = 0.854, p = .014). The lack of association in CAI group may lead to knee instability and increase knee injury risk in people with CAI.
本研究的目的是计算并比较（1）慢性踝关节不稳定（CAI）患者和非慢性踝关节不稳定（CAI）患者在前跳落地任务中的膝关节负荷、（2）肌肉对膝关节负荷的特异性贡献以及（3）膝关节屈曲角度对膝关节负荷和肌肉特异性负荷贡献的影响。八名 CAI 患者和七名健康对照组进行了向前跳跃着地任务。我们收集了三维运动学数据、地面反作用力和肌肉激活情况，并使用了肌肉骨骼模型。结果显示，只有健康对照组的膝关节屈曲角度与膝关节压缩冲力之间存在关联（r = 0.854，p = .014）。CAI 组缺乏关联可能会导致膝关节不稳定，并增加 CAI 患者膝关节受伤的风险。
期刊介绍：
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
